The Heterogeneous Technology Alliance HTA

Electro-optical links for massively parallel multiprocessors SiP

• Background

1965, General Electric GE635, reportedly 1st SMP computer, with 4 processors, up to 2 MIPS 2012, IBM Sequoia BlueGene/Q, with 1.5 M cores,

20 PFLOPS, 7.8 MW. Optical fiber cables, arranged in a 5D-torus network at node board (32 cards) level .

Electro-Optical Links will support next-generation HPC and smart embedded systems

The Heterogeneous Technology Alliance HTA Project Idea: Electro-optical links for massively parallel multiprocessors SiP

EU call:

Project Idea short description: Development of new chip-to-chip communication, based on electro-optical links

Short Description: • Co-optimization of optics and electronics components.

• Non-classical optical receiver & transmitter architectures (small form factor).

• Optical Multi-level AM Modulation.

• Optical clock distribution and synchronization.

And other topic for other applications• Optical generation of ultra-low phase noise mmW signals (Backhaul High order modulation).

Potential Applications:• High Power Computing

• Embedded Systems

• 5G

Competences needed:• Low power Wide Band analog design (up to 25GB/S) for data communication on 28nm and

beyond.

• Actives and passives components models on 28nm and beyond.

• Electro-optical modeling and simulation.

• Heterogeneous integration.
